The Department of Environmental Quality is proposing tougher cleanup rules for Dioxane and hundreds of other pollutants.
The proposal would limit the acceptable levels in drinking water to 7.2 parts per billion. That's significantly lower than Michigan's current requirements. Irwin says this proposal is a more protective standard and helps make the case for continued cleanup of a dioxane plume in Ann Arbor.
State and local officials will be present at an Ann Arbor town hall meeting on April 18th to update residents about the dioxane cleanup plan.
